HEATlNG-DRU M.

SPECIFICATION forming part of Letters Patent No. 374,284, dated December6, 1887.

Application filed March 19, 1887. Serial No. 231,578. (No model.)

To all whom it may concern.-

Be it known that I, J onN W. YATES, a citizen of the United States,residing at Bourbon, in the county of Marshall and State of Indiana,have invented new and useful Improvements in Heating-Drums, of which thefollowing is a specification.

My invention relates to improvements in heating-drums; and it consistsin a certain novel construction and arrangement of parts for service,fully set forth hereinafter, and specifically pointed out in the claims.

My object is to provideaheating-drum which will expose moreheating-surface for the space occupied than any similar device now inuse.

A further object is to provide a drum which will be more economical andthrow out more heat for the amount of fuel used than previous inventionsof the kind.

In the drawings hereto annexed, Figure 1 is a side elevation of thedrum. Fig. 2 is a vertical central section on the line 00 00 of Fig. 1.Fig. 3 is a similar view with the inner pipe lowered to cause a directdraft. Fig. 4 is a horizontal section on the line y of Fig. 1. Fig. 5 isa similar view on the line 2 2, Fig. 1.

Referring to the drawings, in which similar letters denote correspondingparts mall the figures, A designates the central body of the drum,preferably cylindrical in form, to the upper and lower ends of which aresecured the circular plates B G, which extend laterally beyond the sidesof the said body A, thus forming flanges I) c, which are provided with aseries of aligned vertical openings, 1) a, respect ively. A circularopening, 13, is cut in the plate B over the upper end of the body A andcorresponding in size to the said body, and the plate 0 at the lower endof thesaid body is provided with a similar circular opening, G,which isalso adapted to correspond in size to the said body. The lower end ofthe body A is closed by a conical bottom, A, firmly secured in place bysoldering, riveting, or other suitable means, and for a purpose to behereinafter explained. Small pipes or fiues D are passed at the upperand lower ends, respectively, through the aligned openings b c in theflanges b c, and the ends thereof are swaged on the opposite sides ofthe said flanges, and thus there is a series of small pipes or finessurrounding the central body or pipe, A, of the drum. The number offines in the said series is unimportant and may be varied to suit therequirei'nents of the case.

E and G are conical caps fitted, respectively, on the upper and lowerends of the drum by securing the wide ends of the said caps around theedges of the plates B C. It will then be seen that the plates B 0 closethe inner ends of the caps E G.

H is a stove-pipe secured at the upper end in an opening in the lowerend of the cap G and communicating with the interior space thereof, andI is a similar pipe to Hfsecured at the lower end in an opening in theupper end of the cap E in a similar manner to the pipe H. The said pipesH and I may be se cured in the openings in the said conical caps byflaring the ends thereof outwardly around the edges of the saidopenings, as shown in the drawings, or in any other preferred manner. 7

I is a pipe equal in size to the pipes H and I and adapted to fit at theupper end tightly against the lower end of the pipe I, to form a tightjoint at that point, and the said pipe 1 extends down within the drum Anearlyto the bottom thereof.

K is a crossbar secured at the ends to the sides of the pipe I,-near theupper end, by bending the said ends and riveting the same to the pipe,and L is a Vertical rod secured at the lower end in a central opening inthe said bar K by nuts Z Z, screwed on the rod L on opposite sides ofthe said bar K. The said rod 8 L passes vertically through aguide-opening in the center of the crossbar M, placed in the pipe I nearthe lower end thereof, and is provided at the upper end with a ring, N,for a purpose hereinafter explained.

O designates a lever pivoted in the side of the pipe I and adapted tooperate at the in ner end in the ring in the upper end of the rod L, andhaving a locking-arm, P, suspended from the outer end thereof,comprising a bar having a ring or handle, p, on the lower end, and ahook or shoulder, 19, adapted to engage under the edge of the upperplate, B, or a similar projecting edge, when the outer end of thelever-arm is lowered, as shown in Fig. 2.

R represents a series of inwardlyprojecting points or ears, three ormore in number, formed integrally with the plate B, and adapted toimpinge at the inner ends against the sides of the pipe I, so that whenthe said pipe is moved vertically up and down by means of the lever Othe said projections will guide the motion thereof. It will be readilyseen that when the outer end of the lever O is moved the inner pipe, I,will be raised or lowered, and when it is in its raised position theshoulder on the locking-arm P is engaged under the edge of the plate B,and the said pipe is prevented from dropping out of position. Thevertical motion of the lifting-rod L is guided by the opening in theguide-bar M, and therefore the motion of the said pipe I is perfectlyvertical, with no lateral play. The upper edge of the pipe I is slightlybent in, so as to enter the lower end of the pipe I very slightly, andthus form a completely air-tight joint.

The operation of the invention is as follows: If it is desired to have adirect draft, the outer end of the lever-arm O is raised, thus loweringthe inner pipe, I, and the heat and smoke from the fire enter theconical cap G at the lower end of the drum, spread and pass up the smallfines around the outside of the said drum, escape into the cap E at theupper end of the drum, and thence pass up the pipe I directly throughthe opening formed between the upper end of the pipe I and the lower endof the pipe I. (This is clearly shown by the arrows in Fig. 3.) WVhen,however, it is desired to obtain as much heat as possible from the hotair and smoke before they escape up the chimney, lower the outer end ofthe lever 0 and fasten it in the said position. The passage of the airis then as shown by the arrows in Fig. 2-namely, into the cap G, up thefines or pipes around the drum, over the upper edge of the said drum,and down within the drum and on the outside of the pipe I therein, andthence up the pipe I and out. It will be seen that the function of theconical bottom of the drum A is to direct the heat laterally to the sidefines or pipes on the outside and around the said drum, and, also, theeffect of the conical cap E at the upper end of the drum is to deflectthe heat passing up the side pipes and cause it to pass down the openingbetween the inner pipe, I, and the sides of the drum. Thus it will beseen that the smoke and hot air,when coming directly from the fire, arecarried up the flues D, and, these being very small, thesaid hot air isbrought in direct contact with the sides of the said fiues, and then,being deflected down between the pipe 1 and the walls of the centralbody, A, the remaining heat in the air will be utilized to heat the saidbody. Thus in my device I present a large extent of radiating-surfaceand convey the heated air first, when it is in its hottest condition, tothe small fiues which are exposed on all sides to the surrounding air,and as the said fines are small in diameter it will be readily seen thatthe hot air will be brought into close contact with the sides thereofand cause the said sides to become heated to a high degree. and thusradiate a large amount of heat. Further, by isolating the side fiues, D,as described, the air is allowed to circulate entirely around them andthe central drum, and thus there is a great amount of heating-surfaceexposed to the outside air.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

1. The combination, in a heating-drum, of the central body, A, plates BG, secured to the ends thereof and having the openings B O to receivethe body A, and small aligned openings b c therein, flues D, secured atthe ends in the said aligned openings 1) a, conical caps E G, secured tothe said plates, pipe H, to enter the lower cap, G, and pipe I, securedat the lower end in the cap E, substantially as described.
